Chest(2022)
Abstract
SESSION TITLE: ECMO and ARDS in COVID-19 InfectionsSESSION TYPE: Rapid Fire Original InvPRESENTED ON: 10/17/2022 12:15 pm - 1:15 pmPURPOSE: The purpose of the study is to determine the incidence of bloodstream infections in COVID19 patients treated with ECMO in relation to steroid days and days of ECMO cannulation.METHODS: Retrospective analysis of data for COVID19 patients treated with ECMO in a tertiary academic medical center from January 2020 until July 2021 was performed. Data including baseline patients’ characteristics, type, and duration of ECMO support, type and days of steroids used, blood culture results, and organism type were collected. An institutional review board (IRB) approval was obtained before data collection. A two-tailed T-test was used to calculate the P-value, P-value of <0.05 was considered significant.RESULTS: A Total of 34 patients were analyzed, 3 of them were on (Veno-Arterial) VA ECMO and 31 on (Veno-Venous) VV ECMO, 32 out of 34 (94%) patients received steroids (Dexamethasone alone 16 patients, Methylprednisolone 1 patient and 15 patients received multiple steroid types).Seventeen patients had positive blood cultures (50%), average steroid days for patients with positive blood cultures was 21.6 days compared to 11.8 days for patients with negative blood cultures (P-Value:0.01), Average ECMO days for patients with positive blood cultures was 40.5 days compared to 18.8 days for patients with negative blood cultures ( P-Value:0.01). Staphylococcus epidermidis was found in 47% of the cultures, Enterococcus Faecalis was found in 24% of cultures while MRSA, MSSA, and Candida Albicans were found in 6% of cultures.CONCLUSIONS: Bloodstream Infections during ECMO cannulation are common and carry significant morbidity and mortality in patients. Longer ECMO days and longer duration of steroid use were found to be associated with higher rates of bloodstream infections in our patient’s sample. This could be related to the instrumentation risk or immunosuppression from steroids or other factors not evaluated in this study.CLINICAL IMPLICATIONS: Bloodstream infections are common in patients treated with ECMO, the risk of infections increases with longer ECMO and steroid days. Knowledge of such risks and trying to minimize them such as cautious use of steroids might help in the prevention of infections. Further studies are needed to better assess this risk.DISCLOSURES: No relevant relationships by Varun HalaniNo relevant relationships Added 03/21/2022 by Ghassan Kamel, value=HonorariaRemoved 03/21/2022 by Ghassan KamelNo relevant relationships Added 03/22/2022 by Ghassan Kamel, value=HonorariaRemoved 03/22/2022 by Ghassan KamelNo relevant relationships by Ahmad Sharayah SESSION TITLE: ECMO and ARDS in COVID-19 Infections SESSION TYPE: Rapid Fire Original Inv PRESENTED ON: 10/17/2022 12:15 pm - 1:15 pm PURPOSE: The purpose of the study is to determine the incidence of bloodstream infections in COVID19 patients treated with ECMO in relation to steroid days and days of ECMO cannulation.
